I am T2 diabetic, with major depression, insomnia and an as yet undiagnosed gastric problem.
I am often awake 48-72 hours straight. What do I do about meals? Do I need to eat overnight as well as during the day?
I am sorry to hear that you are having such trouble sleeping. Have you had a sleep study done? What is keeping you awake? Thoughts? Restlessness? Waking up when sleeping? I would agree you would want to take your blood sugar and if low eat... Average you should be eating small meals every 4-6 hours to keep an even Blood Sugar. Pleas keep me posted on how you are doing.
If you test your blood sugar when you are awake for a period of time and not eating and it is low than you probably need to have a snack during those times.
Being awake 48-72 hours straight is beyond simple insomnia. You might want to be assessed by a mental health professional to see if you perhaps have Bipolar Disorder rather than Major Depression.
